"This Downtown Las Vegas museum showcases the history of organized crime in the United States. The building is housed in the 1933 U.S. Post Office and Courthouse that held some of the most important and defining trials in the world of organized crime–including the famous Kefauver hearings. Visitors can walk the same halls as federal investigators, informants, and mobsters once did as they wander the collection, which includes weapons, memorabilia from law enforcement and crime bosses, films from court hearings, and even part of a wall from the famous St. Valentine's Day Massacre (complete with bullet holes and blood stains)." - Andrea Bennett
